The present embodiment gathers battery with the use of monomer voltage acquisition module LTC6802 or switch rotation circuit
The monomer voltage of group (the present embodiment uses 12 joint lithium-ion battery monomer series connection).The monomer that will collect
The single-chip microcomputer MC9S08DZ60 that voltage is input in governor circuit, comparing monomer voltage (should with reference voltage
Reference voltage sets according to concrete casing voltage) size.When monomer voltage is less than reference voltage, show list
Body is in under-voltage condition, and governor circuit (Fig. 7) controls switch SW1, SW2 Guan Bi, and put CT1 is simultaneously
High level, CT2 are low level, complete Battery case and mend electricity to monomer side.The now driving chip on total side
U1 starts working with maximum duty cycle (maximum duty cycle of U1 is for 51%), and the voltage V+ of monomer side raises
Thus the electric current flowing through R14 is sent out upper change, this electric current flows through linear optical coupling P1 and controls the PWM ripple of U2 and adjust
The level of pin COMP changes, and makes the dutycycle of PWM ripple change with the change of external voltage, by
Having used Zener diode TL431 in the present embodiment can the output voltage of stabilizing circuit (in the present embodiment
The voltage set is as 4.05V), and then with constant voltage, monomer can be charged.Simultaneously because UC2843
ISENSE control foot (maximum input voltage of this pin is 1V, automatically shuts down more than 1V chip) control
The charging current that equalizing circuit processed is maximum, it is ensured that circuit reliable and stable.When the monomer voltage collected is higher than
During the voltage preset, governor circuit (Fig. 7) controls switch SW1, SW2 Guan Bi, and CT1 is low level, CT2
For high level.Now the driving chip U2 of monomer side is with maximum duty cycle (maximum duty cycle of U2 is for 51%)
Control Q2 to start working so that monomer voltage reduces.The same linear optical coupling P2 of use produces with external voltage
The PWM ripple of change, (voltage now is one stable voltage of Zener diode T1 generation simultaneously
40.25V) giving total bulk charging, the ISENSE foot control monomer of U2 is to the maximum current of total bulk charging.Due to
Two-way flyback DC/DC circuit (Fig. 1) when normal work because the control of PWM ripple makes transformator open
Moment that is logical and that turn off all can produce the biggest transient current and have a great impact circuit, adopts in the present embodiment
Use RCD absorbing circuit, it is ensured that circuit reliable.Exist due to monomer voltage during normal circuit operation
Synchronization likely occurs existing having again a monomer less than setting voltage higher than setting voltage, now circuit without
Method normally works, and for ensureing the reliable of circuit, the present embodiment have employed single chip machine controlling circuit i.e.: sets monomer
Voltage is under-voltage higher than monomer totally to monomer benefit electricity to the priority of total bulk charging higher than monomer during setting voltage
Priority.The now control output end mouth CT1 of single-chip microcomputer (Fig. 7) MC9S08DZ60 of governor circuit
To be high level with CT2 so that audion Q3, Q5 work, and the COMP pin of U1 is pulled low simultaneously,
UC2843 quits work, only the circuit work of monomer laterally total side charging, it is achieved the work of protection circuit
With.
